Previous versions of JBoss EAP could fail to start when run in a Windows 32-bit JDK environment with the default memory settings.
In this release of the product, the default memory settings have been lowered to ensure a successful start on a wider array of JVMs.
Customers who rely on the default JVM settings are advised to review their configuration and adjust JVM parameters based on their requirements.

We fixed standalone startup scripts but same problem applies to domain mode.
Difference with domain start is that startup scripts are ok, but default settings for server.
this settings are part of domain.xml and are as such platform independent.
I would like to change xms & xmx to 1G for both.
